It is the object of this invention to provide novel heat distributors for distributing and directing hot air emitted through floor registers for hot air furnaces. At the presenttime, when such floor registers are used, the

hot air emitted therefrom, being lighter than the air in the room in which the register is situated, will rise directly to the top of the room, thus permitting drafts of cold air ad- 10 jacent the floor of the room. By use of the present invention, the air from such a hot air register can be directed laterally into the room adjacent the floor of the room to prevent cold drafts of air adjacent the floor, and also most of the air from the register can be made to circulate into the room'in a desired direction.

The invention is described in the following specification, made in connection with the accompanying drawings, wherein like reference characters refer to the same or similar parts throughout the various views, and, in which,

Fig. 1 is a vertical section through an embodiment of the invention applied to a floor register for a hot air furnace, the view being taken substantially on the line 1-1 of Fig. 2, as is indicated by the arrow;

Fig. 2 is a plan view of the structure shown in Fig. 1, certain of the parts being broken away to more clearly show the construction thereof.

Referring to the embodiment of the invention illustrated in Figs. 1 and 2 of the drawings, the flooring of a room is designated by the numeral 4 and is supported in the usual manner by floor joists 5. A hot air conduit 6 is mounted in the floor 4 in the usual manner, and a register 7 flush with the floor is applied above the upper end of the conduit 6. Hot air from a hot air furnace (not illustrated) is adapted to be discharged from the conduit 6 through the register 7. The register 7 and upper end of the conduit 6 are illustrated as of circular formation.

In accordance with the present invention, a deflector plate 11 is provided which for use on a round register of the type illustrated, will be of disk-shape. Carried by the plate 50 11 at one edge thereof, is an arcuate plate Serial N0. 338,430.

forming a side flange 12. The plate 11 at its central portion is provided with a curved portion 13 concave on its lower surface and convex on its upper surface and this curved portion has across slot 14 cut therein. A conical support 15, the base of which is adapted to rest on a hot air register such as the register 7, may be used for supporting the plate 11 in spaced relation from the register and for this purpose the support 15 carries a ball 10 at its upper end fitting within the concave part of the curved portion 13. The ball 10 carries a stud 16 which projects upwardly through the opening 14 in the plate and a washer 17 is placed over the stud 16 above the plate 11 and a wing nut 18 threadedon the upper end of stud 16 is adapted to force the washer 17 against the plate 11 to hold the plate in de sired tilted position relative to the support 15.

In use, hot air running upwardly from the conduit 6 through the register 7 will strike the lower side of the plate 11 and will be de-.

flected laterally by the plate adjacent the floor 4. This draft of 'warm air adjacent the floor of the room will prevent drafts of cold air adjacent the floor and will also cause all the air in the room to be thoroughly mixed to prevent layers of air of different temperatures standing at different levels in the room. The air in the room will thus be homogeneously mixed. The flange 12 will cause the hot air to be deflected from between the plate 11- and the top of the register chiefly in one direction. Accordingly, a circulation to the normally coldest spots of the room can be obtained by use of the 'flange 12 or a corresponding vertically disposed plate. As the lower edge of the flange 12 will be spaced slightly above the top of the register 7, it Wlll be seen that a small circulation of air can take place between the lower edge of the flange and the top of the register on the flange side. Accordingly, suificient hot air will be supplied running from the flange side of the plate 11 to prevent drafts of cold air on the floor in this direction. By tilting the plate 11 as indicated in dotted lines, the angle of deflection of hot air from the register as it strikes the plate 11 and flange 12 can be varied to throw the hot air in practically any desired direction. The plate 11 can be rotated relative to the stud 16 by loosenin the wing nut 18, so that the flange 12 may e variably set relative to the support 15. p

The device has been amply demonstrated. 'in actual practice and has been found to-be very successful for the purposes intended. The parts are few and the construction is simple.

It will of course, be understood that various changes may be made in the form, details, arrangement and proportions of the various parts without departing from the scope of the present invention, which, generally stat- 5 ed, consists in the matter shown and described and set forth in the appended claims.

What is claimed is 1. A heat distributor for hot air floor registers comprising a plate, having an aper- 20 tured ball socket portion therein, a support adapted to rest on the floor register and having a ball at its upper end fitting within said ball socket, a stud projecting from the ball of said support through the aperture of said 'ball socket and a nut on said stud for clamping said plate against said socket to secure the plate at a desired tilted angle relative to the support. V

2. The structure defined in claim 1, and a flange projecting downwardly from one side of said plate.

In testimony whereof I aifix my signature.
